Floribunda rose plant named ‘Poulfl003’

ABSTRACT

A new garden rose plant of the floribunda rose class which has abundant, apricot flowers and attractive foliage. This new and distinct variety has shown to be uniform and stable in the resulting generations from asexual propagation.

Botanical Classification: Rosa hybrid.

Variety Denomination: ‘Poulfl003’.

SUMMARY OF THE INVENTION

The present invention constitutes a new and distinct variety of garden rose plant, of the floribunda rose class, that originated from a controlled crossing between the female seed parent ‘Poulsiana’, described and illustrated in U.S. Plant Pat. No. 11,638 issued Nov. 21, 2000, and the male pollen parent, an unnamed seedling.

The two parents were crossed during the summer of 1997, and the resulting seeds were planted in a controlled environment in Fredensborg, Denmark. The new variety is named ‘Poulfl003’.

The new variety may be distinguished from its female seed parent. ‘Poulsiana’ by the following combination of characteristics:

-   -   1. ‘Poulsiana’ has a more compact growth habit than ‘Poulfl003’.     -   2. ‘Poulsiana’ has a petal count of 15 to 20, while ‘Poulfl003’         has 55 to 60 petals.     -   3. ‘Poulsiana’ has a bright yellow flower color, while flower of         ‘Poulfl003’ are apricot.

The new variety may be distinguished from the male pollen parent, by the following combination of characteristics:

-   -   1. The pollen parent has orange flowers. ‘Poulfl003’ has apricot         flowers.     -   2. The pollen parent has more flower petals than ‘Poulfl003’.     -   3. Flowers of the pollen parent are larger in diameter than         those of ‘Poulfl003’.

The objective of the hybridization of this rose variety was to create a new and distinct variety for garden use with unique qualities, such as:

-   -   1. Uniform and abundant apricot flowers;     -   2. Vigorous, but compact growth when propagated both as a budded         rose and on its own roots;     -   3. Disease resistance;     -   4. Dark green attractive foliage.

This combination of qualities is not present in previously available commercial cultivars of this type, known to the inventors, and distinguish ‘Poulfl003’ from all other varieties of which we are aware.

As part of the rose development program, Mogens N. Olesen germinated the seeds from the aforementioned hybridization during winter of 1997 and conducted evaluations on the resulting seedlings in a controlled environment in Fredensborg, Denmark.

‘Poulfl003’ was selected in the spring of 1998 by the inventors as a single plant from the progeny of the aforementioned hybridization.

Asexual reproduction of ‘Poulfl003’ by traditional budding and rooted cuttings was first done by Mogens N. Olesen in the nursery in Fredensborg, Denmark in July, 1998. This initial and other subsequent asexual propagations conducted in controlled environments have demonstrated that the characteristics of ‘Poulfl003’ are true to type and are transmitted from one generation to the next.

DETAILED DESCRIPTION OF THE VARIETY

The following is a description of ‘Poulfl003’, as observed in its growth in a field nursery in Jackson County, Oreg. Observed plants are 2 years of age, and were grown on Rosa multiflora understock. Color references are made using The Royal Horticultural Society (London, England) Colour Chart, 1995, except where common terms of color are used.

For a comparison, several physical characteristics of the rose variety ‘Poululv’, a rose variety from the same inventors described and illustrated in U.S. Plant Pat. No. 15,183 dated Sep. 28, 2004, are compared to ‘Poulfl003’ in Chart 1.

1. A new and distinct variety of rose plant of the floribunda rose class named ‘Poulfl003’, substantially as illustrated and described herein as a distinct and novel rose variety due to its abundant apricot flowers, dark green foliage, disease resistance, and extended period of bloom.
